摘　　要：为解决部分地铁车辆在长期运营后出现轮对异常磨耗的问题,对地铁车辆电空制动配合不良、信号控制指令错误导致的轮对异常磨耗进行情况调查和原因分析,提出了修改软件控制逻辑来减少地铁车辆65 km/h制动时空气制动的补充以及对空气制动系统的控制和自动驾驶模式下控车软件进行优化的改进措施。实际运用表明:改进措施效果明显,很好地解决了地铁车辆轮对异常磨耗的问题。In order to solve the abnormal wheelsets wear of some metro vehicles after long-term operation, the abnormal wheelsets wear caused by poor electro-pneumatic braking coordination and signal control instruction error of metro vehicles was investigated and analyzed. The improvement measures of modifying software control logic to reduce the supplement of the air braking of metro vehicles at 65 ~ was proposed, and the control of air brake system and automatic driving mode control software were optimized. Practical application showed that the improvement measures had obvious effect and solved the abnormal wear problem of metro vehicle wheelsets.
